4.7.6 Multiturn Limit Setting
4-96
• Variation of multiturn data when the multiturn limit value is other than 65535 (factory
setting).
If the servomotor rotates in the negative direction from 0, the multiturn data will change to
the value set for Pn205. If the servomotor rotates in the positive direction from the value set
in Pn205, the multiturn data will change to 0. Set Pn205 to m-1.
Turn the power OFF and then back ON after changing the setting of parameter Pn002.2 or Pn205.
The multiturn limit value in the Encoder is factory set to 65535, the same as the SERVO-
PACK. If the multiturn limit value in the SERVOPACK is changed with Pn205 and then the
SERVOPACK power is turned OFF and ON, the following alarm will occur.
Alarm Name: Multiturn Limit Disagreement
Note: OFF: Signals are high level. ON: Signals are low level.
When this alarm occurs, the multiturn limit in the Encoder must be changed. The auxiliary
function mode of the Digital Operator is used to change this setting. It can also be set from a
personal computer using the Monitor Software.
The procedure to set the multiturn limit in the Encoder using the Digital Operator is pro-
vided next. Refer also to Chapter 6 Using the Digital Operator.
The multiturn limit setting in the Encoder can be changed only when the Multiturn Limit Disagreement
alarm has occurred. After changing the setting, turn the power supply OFF and then back ON.
